7.2 Subject to the procedures set out in the Procedures Memorandum, for the purposes of clause 3, each of the Principal Paying Agent and the Registrar is entitled to treat a telephone, telex or facsimile communication from a person purporting to be (and who the Principal Paying Agent or the Registrar, as the case may be, believes in good faith to be) the authorised representative of the Issuer named in the list referred to in, or notified pursuant to, clause 23.7 below, or any other list duly provided for such purpose by the Issuer to the Principal Paying Agent, as sufficient instructions and authority of the Issuer for the Principal Paying Agent or the Registrar to act in accordance with clause 3 save where the Principal Paying Agent or the Registrar has received, pursuant to clause 23.7, from the Issuer notice to the effect that such person is no longer an authorised representative of the Issuer.

7.3 Execution in facsimile of any Notes and any photostatic copying or other duplication of master Global Notes (in unauthenticated form but executed manually on behalf of the Issuer) shall be binding upon the Issuer in the same manner as if the Notes were signed manually by the Issuer. In the event that a person who has signed a master Global Note or master Definitive Registered Note held by the Principal Paying Agent or the Registrar, as the case may be, on behalf of the Issuer ceases to be authorised as described in clause 23.7, each of the Principal Paying Agent and the Registrar, shall (unless the Issuer gives notice to the Principal Paying Agent or the Registrar, as the case may be, that Notes signed by that person do not constitute valid and binding obligations of the Issuer or otherwise until replacements have been provided to the Principal Paying Agent or the Registrar, as the case may be), continue to have authority to authenticate and issue Notes signed by that person, and the Issuer hereby warrants to each of the Principal Paying Agent and the Registrar that such Notes shall be valid and binding obligations of the Issuer. Promptly upon such person ceasing to be authorised, the Issuer shall provide the Principal Paying Agent with replacement master Temporary Bearer Global Notes and Permanent Bearer Global Notes and shall provide the Registrar with replacement master Registered Global Notes and the Principal Paying Agent and the Registrar, as the case may be, shall, upon receipt of such replacements, cancel and destroy the master Notes held by them which are signed by such person and shall provide the Issuer with a certificate of destruction in respect thereof, specifying the master Notes so cancelled and destroyed.

7.5 If the Principal Paying Agent pays an amount (the “Advance”) to the Issuer on the basis that a payment (the “Payment”) has been or will be received from a Dealer and if the Payment is not received by the Principal Paying Agent on the date the Principal Paying Agent pays the Issuer, the Issuer shall repay to the Principal Paying Agent as agent on behalf of the Issuer the Advance (unless prior to this repayment the Payment is received by the Agent) and shall pay interest on the Advance (or the unreimbursed portion thereof) from (and including) the date such Advance is made to (but excluding) the earlier of repayment of the Advance or receipt by the Principal Paying Agent of the Payment (at a rate quoted at that time by the Principal Paying Agent as its cost of funding the Advance provided that evidence of the basis of such rate is given to the Issuer. For the avoidance of doubt, the Principal Paying Agent shall not be obliged to pay any amount to the Issuer if it has not received satisfactory confirmation that it is to receive such amount from a Dealer.

7.6 Except in the case of issues where the Principal Paying Agent does not act as receiving bank for the Issuer in respect of the purchase price of the Notes being issued, if on the Issue Date a Dealer does not pay the full purchase price due from it in respect of any Note (the “Defaulted Note”) and, as a result, the Defaulted Note remains in the Principal Paying Agent’s distribution account with Euroclear and/or Clearstream, Luxembourg or the Portuguese Paying Agent’s account with Interbolsa, as the case may be, after such Issue Date, the Principal Paying Agent will continue to hold the Defaulted Note to the order of the Issuer. The Principal Paying Agent shall notify the Issuer forthwith of the failure of the Dealer to pay the full purchase price due from it in respect of any Defaulted Note and, subsequently, shall (i) notify the Issuer forthwith upon receipt from the Dealer of the full purchase price in respect of such Defaulted Note and (ii) pay to the Issuer the amount so received.

7.7 The Issuer (and where the Issuer is PTIF, failing which PT) shall procure that a sufficient quantity of executed but unauthenticated blank Notes is at all times available to the Principal Paying Agent for the purpose of issue under this Agreement.

7.8 The Issuer shall give to the Principal Paying Agent by facsimile transmission or telex or through the CitiTreasury Manager system details of any Notes to be issued by it under this Agreement and all such other information as the Principal Paying Agent may require for it to carry out its function as contemplated by this clause, by not later than 3.00 p.m. (London time) three Business Days (as defined below) prior to the proposed Issue Date, or such later time or date as may subsequently be agreed between the Issuer and the Principal Paying Agent.

7.9 The Principal Paying Agent shall receive notification by facsimile transmission or telex or through the CitiTreasury Manager system from the Dealer who has arranged to purchase Notes from the Issuer. Such Notification to be received in sufficient time to enable delivery to be made as contemplated herein and in no case later than 3.00 p.m. (London time) three Business Days prior to the proposed Issue Date, or such later time as may be agreed between the Principal Paying Agent and the relevant Dealer, that payment by it to the Issuer of the purchase price of any Notes has been or will be duly made against delivery of such Notes and (if applicable) details of their securities account.

8. PAYMENTS

8.1 Payments in respect of Notes other than Book Entry Notes

(a) The Issuer will on each date on which any payment in respect of any Note becomes due under the Terms and Conditions, transfer to an account specified by the Principal Paying Agent such amount in the relevant currency in immediately available and freely transferable funds as shall be sufficient for the purposes of such payment in funds settled through such payment system as the Principal Paying Agent and the Issuer may agree.

(b) Any funds paid by or by arrangement with the Issuer to the Principal Paying Agent pursuant to sub-clause 8.1 shall be held in the relevant account referred to in sub-clause 8.1 for payment to the Noteholders, Receiptholders or Couponholders, as the case may be, until any Notes or matured Receipts and Coupons become void under Condition 9. In that event the Principal Paying Agent shall forthwith repay to the Issuer sums equivalent to the amounts which would otherwise have been repayable on the relevant Notes, Receipts or Coupons.

(c) The Issuer will ensure on the second Business Day (as defined below) immediately preceding the date on which any payment is to be made to the Principal Paying Agent pursuant to sub-

(ii) if it receives unconditionally the full amount of any sum payable in respect of the Notes, Receipts or Coupons after such date.

The Principal Paying Agent shall, at the expense of PTIF or PT forthwith upon receipt of any amount as described in subparagraph (ii), cause notice of that receipt to be published under Condition 15.

(e) The Principal Paying Agent shall ensure that payments of both principal and interest in respect of a Temporary Bearer Global Note will only be made if certification of non-U.S. beneficial ownership as required by U.S. Treasury regulations has been received from Euroclear and/or Clearstream, Luxembourg in accordance with the terms thereof.

(f) Unless it has received notice pursuant to sub-clause (d)(i) above, each Paying Agent (other than the Portuguese Paying Agent) shall pay or cause to be paid all amounts due in respect of the Notes on behalf of the Issuer in the manner provided in the Terms and Conditions. If any payment provided for in sub-clause (a) is made late but otherwise in accordance with the provisions of this Agreement, the relevant Paying Agent shall nevertheless make payments in respect of the Notes as aforesaid following receipt by it of such payment.

(g) If for any reason the Principal Paying Agent considers in its sole discretion that the amounts to be received by it pursuant to sub-clause (a) will be, or the amounts actually received by it pursuant thereto are, insufficient to satisfy all claims in respect of all payments then falling due in respect of the Notes, no Paying Agent shall be obliged to pay any such claims until the Principal Paying Agent has received the full amount of all such payments.

(h) Without prejudice to sub-clauses (f) and (g), if the Principal Paying Agent properly pays any amounts to the holders of Notes, Receipts or Coupons or to any other Paying Agent in accordance with this Agreement or the Terms and Conditions or at the request of the Issuer at a time when it has not received payment in full in respect of the relevant Notes in accordance with sub-clause (a) (the excess of the amounts so paid over the amounts so received being the “Shortfall”), the Issuer will, in addition to paying amounts due under sub-clause (a), pay to the Principal Paying Agent on demand interest (at a rate which represents the Principal Paying Agent’s cost of funding the Shortfall) on the Shortfall (or the unreimbursed portion thereof) until the receipt in full by the Principal Paying Agent of the Shortfall. If on the due date for payment of any amount in respect of the Notes, the Principal Paying Agent has not received payment in full in respect of the relevant Notes in accordance with sub-clause (a), the Principal Paying Agent shall forthwith notify PTIF and PT.

(i) The Principal Paying Agent shall on demand promptly reimburse each other Paying Agent for payments in respect of Notes properly made by such Paying Agent in accordance with this Agreement and the Terms and Conditions unless the Principal Paying Agent has notified the

relevant Paying Agent, prior to its opening of business on the due date of a payment in respect of the Notes, that the Principal Paying Agent does not expect to receive sufficient funds to make payment of all amounts falling due in respect of such Notes.

(j) Whilst any Notes are represented by Global Notes, all payments due in respect of such Notes shall be made to, or to the order of, the holder of the Global Notes, subject as provided in sub-clause (k) and subject to and in accordance with the provisions of the Global Notes. On the occasion of any such payment (i) in the case of a CGN, the Paying Agent to which such Bearer Global Note was presented for the purpose of making such payment shall cause the appropriate Schedule to the relevant Bearer Global Note to be annotated so as to evidence the amounts and dates of such payments of principal and/or interest as applicable or (ii) in the case of any Bearer Global Note which is a NGN, the Paying Agent shall instruct Euroclear and Clearstream, Luxembourg to make appropriate entries in their records to reflect such payment.

(k) If the amount of principal and/or interest then due for payment is not paid in full (otherwise than by reason of a deduction required by law to be made therefrom or a certification required by the terms of a Note not being received), (i) the Paying Agent to which a Bearer Global Note, Receipt or Coupon (as the case may be) is presented for the purpose of making such payment shall, unless the Bearer Global Note is a NGN, make a record of such shortfall on the relevant Note, Receipt or Coupon and such record shall, in the absence of manifest error, be prima facie evidence that the payment in question has not to that extent been made; (ii) in the case of payments of interest on Registered Notes, the Registrar shall make a record in the Register and such record shall, in the absence of manifest error, be prima facie evidence that the payment in question has not to that extent been made; or (iii) in the case of any Bearer Global Note which is a NGN, the Principal Paying Agent shall instruct Euroclear and Clearstream, Luxembourg to make appropriate entries in their records to reflect such shortfall in payment.

8.2 Payments in respect of Book Entry Notes

(a) In order to provide for the payment of principal and/or interest in respect of the Book Entry Notes as the same becomes due and payable, PT shall pay to the Principal Paying Agent on the Business Day (the “Relevant Day”) prior to the date on which such payment becomes due (the “Payment Date”), an amount equal to the amount of principal and/or (as the case may be) interest and other relevant amounts including Interbolsa fees falling due in respect of the Book Entry Notes on such date. The Principal Paying Agent shall transfer to the Portuguese Paying Agent on the same day, an amount equal to the amount of principal and/or (as the case may be) interest and other relevant amounts including Interbolsa fees falling due in respect of the Book Entry Notes on such date.

(b) Each amount payable by PT under Clause 8.2(a) shall be paid unconditionally by credit transfer in the currency in which the Book Entry Notes are denominated according to the procedures and regulations applicable by Interbolsa, in immediately available, freely transferable, cleared funds not later than 1.00 p.m. (Lisbon time) on the Relevant Day to the account held by the Principal Paying Agent as notified by the Principal Paying Agent, or such other account as the Principal Paying Agent may from time to time specify by notice to PT. PT shall, before 1.00 p.m. (Lisbon time) on the second Lisbon Business Day before the due date of each payment by it under Clause 8.2(a), procure that the bank effecting payment for it confirms by authenticated SWIFT message to the Principal Paying Agent (SWIFT address: CITIGB2L) the payment instructions relating to such payment.

(c) PT shall, no later than the seventh Lisbon Business Day preceding the Payment Date, provide the Principal Paying Agent with an irrevocable confirmation that it will transfer to the Principal Paying Agent, in accordance with Clause 8.2(a) and Clause 8.2(b) above, the sufficient amount for those payments to be made, and the Principal Paying Agent shall provide a copy of such irrevocable confirmation to the Portuguese Paying Agent.

(d) Subject to receipt of funds pursuant to Clause 8.2(a) and the procedures set out in the Offering Circular, the Portuguese Paying Agent acting through its specified office shall make payments of interest or, as the case may be, principal in respect of the Book Entry Notes in accordance with the Terms and Conditions, provided however that:

(i) by no later than 15 days prior to any date on which a payment (either of principal or interest) is scheduled to be made (the “Issuer Information Date”), PT shall provide Interbolsa with a written notification that the relevant payment will be made and with all necessary information for the purpose of carrying out such payment, including the identity of the Portuguese Paying Agent;

(ii) no later than five Lisbon Business Days following the Issuer Information Date, the Portuguese Paying Agent shall provide, or have provided previously for all payments due under the relevant Tranche of Book Entry Notes, a written confirmation to Interbolsa stating that it will comply with the functions of a paying agent in relation to such payment or payments (either of principal or interest, as the case may be), subject to receipt by the Portuguese Paying Agent of the irrevocable confirmation mentioned in Clause 8.2(c) prior to the seventh Lisbon Business Day preceding the date of the relevant payment (whether of principal or interest). The Portuguese Paying Agent shall provide PT with a copy of any payment confirmation provided to Interbolsa pursuant to this Clause 8.2(d)(ii);

(iii) payment of principal and interest in respect of the Book Entry Notes will be transferred, on the Payment Date and according to the procedures and regulations applicable by Interbolsa, from the payment current account held with the Bank of Portugal or with such other institution as may be acceptable to Interbolsa by the Portuguese Paying Agent to the payment current accounts held with the Bank of Portugal or with such other institution as may be acceptable to Interbolsa by the relevant Affiliate Member of Interbolsa and from the accounts thereof to the accounts of the holders of Book Entry Notes or of Euroclear or Clearstream, Luxembourg with such Affiliate Member of Interbolsa, as the case may be;

(iv) nothing contained in this Agreement shall require the Principal Paying Agent and the Portuguese Paying Agent to expend or risk its own funds or incur any liability in the performance of its duties or the exercise of any right, power, authority or discretion hereunder if it has justified grounds for believing that the repayment of such funds or adequate indemnity against, or security for, such risk or liability is not reasonably assured to it;

(v) in particular, each of the Principal Paying Agent and the Portuguese Paying Agent shall not be obliged at any time (but shall be entitled at its discretion) to make payments of principal or interest in respect of the Book Entry Notes until it has received the full amount of any payment due to it under Clause 8.2(a); and

(vi) the Portuguese Paying Agent will not be responsible for making any deduction or withholding from any payment which it makes under this Agreement for or on

account of any present or future taxes, duties or charges if and to the extent so required by applicable law, which shall be made by each of the Affiliate Members of Interbolsa, in which event such Affiliate Member of Interbolsa shall make such payment after such withholding or deduction has been made and shall account to the relevant authorities for the amount so withheld or deducted.

(e) If the Principal Paying Agent or Portuguese Paying Agent makes any payment in accordance with Clause 8.2(d), it shall be entitled to appropriate for its own account out of the funds received by it under Clause 8.2(a) an amount equal to the amount so paid by it.

(f) Subject to subclauses 8.2(d)(iv) and 8.2(d)(v) if the Principal Paying Agent or the Portuguese Paying Agent makes a payment in respect of Book Entry Notes on or after the due date for such payment under the Terms and Conditions at a time at which it has not received the full amount of the relevant payment due to it under Clause 8.2(d)(iii), PT shall on demand pay to the Principal Paying Agent:

(i) the amount so paid out by the Principal Paying Agent or the Portuguese Paying Agent and not reimbursed to it out of the funds appropriated by it pursuant to Clause 8.2(e); and

(ii) interest on such amount from the date on which the Principal Paying Agent or the Portuguese Paying Agent made such payment until the date of reimbursement of such amount (and the Principal Paying Agent will, upon request, provide evidence of the interest, cost, loss or expense which it incurs),

provided, however, that any payment made under subclause 8.2(f)(i) shall satisfy pro tanto PT’s obligations under Clause 8.2(d).

(d) The Principal Paying Agent shall use its best endeavours to cause each Rate of Interest, Interest Amount and Interest Payment Date and all other amounts, rates and dates which it is obliged to determine or calculate under the Terms and Conditions to be published as required in accordance with the Terms and Conditions as soon as possible after their determination or calculation.

Notes of any Series may specify additional duties and obligations of any Agent, the performance of which will be agreed between the Issuer and the relevant Agent prior to the relevant Issue Date.

9.2 Interest Determination, Screen Rate Determination including Fallback Provisions

(a) Where Screen Rate Determination is specified in the applicable Final Terms as the manner in which the Rate of Interest is to be determined, the Rate of Interest for each Interest Period will, subject as provided below, be either:

(i) the offered quotation; or

(ii) the arithmetic mean (rounded if necessary to the fifth decimal place, with 0.000005 being rounded upwards) of the offered quotations,

(expressed as a percentage rate per annum), for the Reference Rate which appears or appear, as the case may be, on the Relevant Screen Page as at 11.00 a.m. (London time) on the Interest Determination Date in question plus or minus (as indicated in the applicable Final Terms) the Margin (if any), all as determined by the Principal Paying Agent. If five or more such offered quotations are available on the Relevant Screen Page, the highest (or, if there is more than one such highest quotation, one only of such quotations) and the lowest (or, if there is more than one such lowest quotation, one only of such quotations) shall be disregarded by the Principal Paying Agent for the purpose of determining the arithmetic mean (rounded as provided above) of such offered quotations.

(b) If the Relevant Screen Page is not available or if, in the case of clause 9.2(a)(i), no such offered quotation appears or, in the case of clause 9.2(a)(ii), fewer than three such offered quotations appear, in each case as at the time specified in clause 9.2(a) the Principal Paying Agent shall request the principal London office of each of the Reference Banks to provide the Principal Paying Agent with its offered quotation (expressed as a percentage rate per annum)

(c) If on any Interest Determination Date one only or none of the Reference Banks provides the Principal Paying Agent with such offered quotations as provided in the preceding paragraph, the Rate of Interest for the relevant Interest Period shall be the rate per annum which the Principal Paying Agent determines as being the arithmetic mean (rounded if necessary to the fifth decimal place, with 0.000005 being rounded upwards) of the rates, as communicated to (and at the request of) the Principal Paying Agent by the Reference Banks or any two or more of them, at which such banks were offered, at 11.00 a.m. (London time) on the relevant Interest Determination Date, deposits in the Specified Currency for a period equal to that which would have been used for the Reference Rate by leading banks in the London inter-bank market (if the Reference Rate is LIBOR) or the Euro-zone inter-bank market (if the Reference Rate is EURIBOR) plus or minus (as indicated in the applicable Final Terms) the Margin (if any) or, if fewer than two of the Reference Banks provide the Principal Paying Agent with such offered rates, the offered rate for deposits in the Specified Currency for a period equal to that which would have been used for the Reference Rate, or the arithmetic mean (rounded as provided above) of the offered rates for deposits in the Specified Currency for a period equal to that which would have been used for the Reference Rate, at which, at 11.00 a.m. (London time) on the relevant Interest Determination Date, any one or more banks (which bank or banks is or are in the opinion of the Issuer suitable for such purpose) informs the Principal Paying Agent it is quoting to leading banks in the London inter-bank market (if the Reference Rate is LIBOR) or the Euro-zone inter-bank market (if the Reference Rate is EURIBOR) plus or minus (as indicated in the applicable Final Terms) the Margin (if any), provided that, if the Rate of Interest cannot be determined in accordance with the foregoing provisions of this paragraph, the Rate of Interest shall be determined as at the last preceding Interest Determination Date (though substituting, where a different Margin is to be applied, as indicated in the applicable Final Terms, to the relevant Interest Period from that which applied to the last preceding Interest Period, the Margin relating to the relevant Interest Period, in place of the Margin relating to that last preceding Interest Period).

(d) If the Reference Rate from time to time in respect of Floating Rate Notes is specified in the applicable Final Terms as being other than LIBOR or EURIBOR, the Rate of Interest in respect of such Notes will be determined as provided in the applicable Final Terms.

10. NOTICE OF ANY WITHHOLDING OR DEDUCTION

10.1 If the Issuer is, in respect of any payment, compelled to withhold or deduct any amount for or on account of taxes, duties, assessments or governmental charges as specifically contemplated under the Terms and Conditions, it shall give notice thereof to the Principal Paying Agent, the Trustee and the Registrar as soon as it becomes aware of the requirement to make such withholding or deduction and shall give to the Principal Paying Agent, the Trustee and the Registrar such information as any of them shall require to enable it to comply with such requirement.
